Magnetic and Hydraulic-Magnetic Circuit Breaker 8340-G2...

Description

Single and two pole magnetic circuit breakers with trip-free

mechanism and push/pull on/off manual actuation. A choice of fast

magnetic only or hydraulically delayed switching characteristics (S-

type MO or HM CBE to EN 60934) ensures suitability for a wide range

of applications. Convenient threadneck panel or plug-in mounting, and

with a white push button indicator band showing clearly the tripped/off

position. Available with auxiliary contacts (1 x N/O, 1 x N/C) for status

signalling and fitted with an unprotected shunt tap terminal as standard.

Approved to CBE standard EN 60934 (IEC 60934).

Typical application

Control equipment, communications systems, power semiconductors.
